Laser diode collimating system - FUJIFILM ELECTRONIC IMAGING ...A laser diode collimating system comprises a collimating lens for receiving a laser beam from a laser diode LD. First and second orthogonally arranged cylindrical lenses are provided through which the laser beam passes.
Focusing a Collimated Laser Beam. As a first example, we look at a common application, the focusing of a laser beam to a small spot. The situation is shown in Figure 1. Here we have a laser beam, with radius y 1 and divergence θ 1 that is focused by a lens of focal length f. From the figure, we have θ2 = y1/f.
Select A Collimating Lens for the Laser Diode. Since the laser diode' output light is highly divergent, it requires the use of collimating optics. Generally, choose aspheric lenses reducing the spherical aberration for better collimated beam. Here' an example of the major specifications to consider for choosing the right lens for a given ...
Collimated laser diodes are an assembly of a laser diode with a specified collimating lens within a small package. World Star Tech offers collimated laser diodes from 400nm to 1064nm with a standard or custom design. Our experienced design team will offer custom laser diode collimators with desired divergence and beam size and shape.
The smallest spot size of a laser diode beam is analyzed for various beam delivery distances after being collimated and focused. A simple way of calculating the spot size is found. View
Ways to Collimate a Laser Beam. Fig. 1. An aspheric lens is being used to collimate a laser diode beam. Quite often CW lasers have a short cavity. The resonator of microchip DPSS lasers may vary from less than a millimeter to few millimeters. Cavities of single-mode laser diodes are in the range of hundreds of microns.
Laser diode beam collimators do not only consist of optical elements, but also contain mechanical parts for fixing the position of the collimation lens and any other optics, and also the laser diode. Often, they are made such that laser diodes with a certain housing (e.g., TO can for low-power emitters) can conveniently be fixed to the ...

Collimators for Single-emitter Laser Diodes Most available laser diode collimators are designed for use with low-power single-emitter edge-emitting laser diodes. For example, such devices are required in laser pointers. Figure 1: Simple laser diode collimator. We first consider only one direction of the emission (horizontal or vertical).

Collimation tubes are a very common mount for TO can laser diodes; they include an aspheric lens for collimation and are typically installed into systems with external temperature regulation. Cage-compatible collimation kits allow the user to integrate Ø5.6 mm, Ø9 mm, and TO3 can lasers into a 30 mm cage system.

For example, the NA of the A390-B or A390TM-B is 0.53, which is more than twice the approximation of the NA of a laser diode (0.26) so it can be used for this laser diode. Note that the focal length of these lenses is 4.6 mm, so the collimated long axis beam diameter is about 2.5 mm.

The most simple and popular way is to collimate a laser diode beam by using a single aspheric lens. (see Fig. 1). The larger is the focal length of this lens, the larger will the beam diameter be after collimation. Furthermore, if a certain beam adjustment has to be made, for example in order to expand the beam radius of a collimated beam, two ...
